Abstract: The antibacterial activity of aqueous and methanol extracts of leaves/shoots of five salt marsh halophytes and six mangroves was studied against methicillin resistant, clinical isolates of Staphylococcus aureus. There was a clear comparability between the salt marsh halophytes and mangroves in their antibacterial action. The mangrove plants possessed higher antibacterial potency than the salt marsh halophytes. The highest activity was recorded with the methanol extract of Excoecaria agallocha followed by the methanol extracts of Aegiceras corniculatum, Lumnitzera racemosa and Ceriops decandra. The minimum inhibitory concentration (MIC) values ranged from 0.125 to 4 mg/mL and 1 to 16 mg/mL for methanol and aqueous extracts, respectively. Further separation of active principle from the potent mangrove plant will be useful for the control of drug resistant strains of S. aureus.

Abstract: The antibacterial activity of the leaves and bark of mangrove plants, Avicennia marina, A. officinalis, Bruguiera sexangula, Exoecaria agallocha, Lumnitzera racemosa, and Rhizophora apiculata was evaluated against antibiotic resistant pathogenic bacteria, Staphylococcus aureus and Proteus sp. Soxhlet extracts of petroleum ether, ethyl acetate, ethanol and water were prepared and evaluated the antibacterial activity using agar diffusion method. Most of the plant extracts showed promising antibacterial activity against both bacterial species. However, higher antibacterial activity was observed for Staphylococcus aureus than Proteus sp. The highest antibacterial activity was shown by ethyl acetate of mature leaf extracts of E. agallocha for Staphylococcus aureus. All ethyl acetate extracts showed higher inhibition against S. aureus while some extracts of chloroform, ethyl acetate and ethanol gave inhibition against Proteus sp. None of the petroleum ether and aqueous extracts showed inhibition against Proteus sp. All fresh plant materials did also show more antibacterial activity against both bacterial strains than did dried plant extracts. Antibacterial activity of fresh and dried plant materials reduced for both bacterial strains with time after extraction. Since L. racemosa and A. marina gave the best inhibition for bacterial species, they were used for further investigations. Charcoal treated plant extracts of L. racemosa and A. marina were able to inhibit both bacterial strains more than those of untreated plant extracts. Phytochemical screening of mature leaf, bark of L. racemosa and leaf extracts of A. marina has been carried out and revealed that leaf and bark contained alkaloids, steroids, triterpenoids and flavonoids. None of the above extracts indicate the presence of saponins and cardiac glycosides. Separated bands of extracts by TLC analysis showed antibacterial activity against S. aureus.

TL;DR: Recent investigations on the biological activities of extracts and phytochemicals identified from mangroves and their associates as antimicrobial, antiviral, antioxidant, anticancer and many other properties like antiproliferative, insecticidal, antimalarial, antifeedant, central nervous system depressant and anti-plasmodial are examined.

Abstract: Mangrove forests are salt tolerant plants confined to the coastal areas and occupy only 5% of the total forest areas of the world. These are the most hostile environment with fluctuating tidal and saline regime and a limited plant species can survive under such condition. Nevertheless, these plants are most valuable resources and provide economic and ecological benefits to the coastal people. Several mangrove species have been used in traditional medicine or have few applications as insecticide and pesticide. Mangroves are biochemically unique, producing wide array of natural products with unique bioactivity. They possess active metabolites with some novel chemical structures which belong to diverse chemical classes such as alkaloids, phenol, steroids, terpenoids, tannins, etc. The present review examines recent investigations on the biological activities of extracts and phytochemicals identified from mangroves and their associates as antimicrobial, antiviral, antioxidant, anticancer and many other properties like antiproliferative, insecticidal, antimalarial, antifeedant, central nervous system depressant and anti-plasmodial etc. The present article also emphasizes and creates an awareness of potential mangroves and their associates as a source of novel medicines, agrochemicals and source of many biologically active compounds.

Abstract: This review examines the chemical compositions and bioactivities of mangrove plants belonging to the Rhizophoraceae family. The Rhizophoraceae family of true mangrove plants is the most common and is also widely distributed species. It consists of 24 species across four genera. Of the 24 species, 12 species remain unexamined for their phytochemical constituents. There have been 268 metabolites reported from 16 species. The key phytochemical constituents identified across the family are the diterpenoids and triterpenoids. The major diterpenoids include pimaranes, beyeranes, kaurenes, dolabranes and labdanes whereas the significant triterpenoids are lupanes, dammaranes and oleananes. Disulphides, dolabranes and labdanes are considered to be the chemotaxonomic markers of the genera Bruguiera, Ceriops and Rhizophora respectively.

Abstract: In the present work, the antioxidant and antibacterial activities of methanolic, ethanolic and chloroform crude extract of leaves and barks of Bruguiera gymnorrhiza were investigated. The antioxidant activity of the crude extracts were evaluated using the enzymatic and non enzymatic methods namely superoxide dismutase determination, reducing power assay and 2, 2-diphenyl-1-picrylhydrazil free radical scavenging assays. Folin-ciocalteu reagent method was used to estimate the amount of total phenolic compounds of the extracts. Ethanol extract of barks showed the best result in all antioxidant assays which was positively co-related with the total phenolic contents. There was no significant difference between the IC 50 value of ethanol extract of bark and the ascorbic acid. Escherichia coli , Pseudomonas aeruginosa , Staphylococcus aureus and Bacillus cereus were used as the test pathogenic bacteria in this study. Both ethanol and methanol extracts could inhibit the growth of all pathogenic bacteria while chloroform extract of leaves showed no activity against any bacteria. Antimicrobial effect of ethanol extract of barks was higher than all other extracts.

Abstract: We studied a tropical mangrove ecosystem, situated at Pichavaram, southeast India. We found 13 species of mangrove trees, with Avicennia marinaand Rhizophora species predominant, besides 73 spp. of other plants, 52 spp. of bacteria, 23 spp. of fungi, 82 spp. of phytoplankton, 22 spp. of seaweeds, 3 spp. of seagrass, 95 spp. of zooplankton, 40 spp. of meiobenthos, 52 spp. of macrobenthos, 177 spp. of fish and 200 spp. of birds. The bacteria performed activities like photosynthesis, methanogenesis, magnetic behaviour, human pathogens and production of antibiotics and enzymes (arysulphatase, L-glutaminase, chitinase, L-asparaginase, cellulase, protease, phosphatase). The microzooplankton included tintinnids, rotifers, nauplius stages of copepods and veliger larvae of molluscs, with a predominance of tintinnids. Tintinopsis spp. alone accounted for 90% of abundance. The macrozooplankton consisted of 95% of copepods and coelenterates. The meiofauna was rich with nematodes (50–70% of the component), followed by foramifera. The macrofauna included polychaetes, bivalves, gastropods, tanaids, isopods, amphipods, cirripedes, crabs, hermit crabs and shrimps. The mangrove harboured a large number of juvenile fishes, especially during summer and post-monsoon. The water was fertile and productive in having several fold-higher levels of nutrients, microbes, plankton and other biological resources, than the adjoining estuarine, backwater and neritic environments. The gross primary production was 8 g cm-3 d-1; about 21% of which was contributed by phytoplankton of 5–10 μm size. Unfortunately, 90% of the mangrove cover in the study area was degraded. Possible factors that cause degradation of the ecosystem are detailed and remedial measures suggested. Techniques for regeneration of the degraded areas are proposed.
